SPECIFICATION forming part of Letters Patent No. 320,570, dated June 23, 1885.

Application filed hlallcll 31, 1685. (No model.)

To all whom it may concern:

Beit known that I, JosEPH MARoUs, a subject of the Emperor of Germany, residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in WVindmills, of which the following is a specification, reference being had therein to the accompanying drawings.

. My invention relates'to an improved windmill.

The object of the invention is to improve the general construction of the device, and to provide suitable mechanism for locking the parts, so as to avoid the possibility of the mill being operated when not desired.

To the accomplishment of the above the invention consists of the novel devices and combination of devices, as will be described and claimed. a

Reference will be made to the accompanying drawings, in which "Figure 1 is a plan view, showing .the mill ready for operation; Fig. 2, a similar view with the parts locked in position not to be affected by the wind; Fig. 3, an elevation of Fig. 1; Fig. 4, a similar view of Fig. 2, and Fig. 5 a sectional detail.

Like letters refer to like parts in each view.

A represents a suitable base,in which a vertical shaft, B, is mounted, and C C suit able braces or supports. At a point near its upper end shaft B is provided with a ring or flange, a, to which a series of radiating curved arms, D, are secured. A similar flange is secured to shaft B, at a suitable point below the one a, and to this last-named one a series of radiating curved arms, D, are secured, arms D D forming the frame-work of the wings of the mill.

Each arm D D is provided with a series of bearing-points, 6, Figs. 1 2, into which the trunnions of vertical flaps E have bearing, these flaps being thus pivotally mounted between thearms D D.

Protruding from one side edge of each arm D are a series of pins, C, there being one for each flap E, to limit their movement, as will be described.

Mounted upon shaft B at a suitable point below arms D is a sleeve, F, mounted upon such shaft in such a manner that it will be revolved therewith by friction unless resistance is offered.

- Sleeve F is provided at its upper and lower ends, respectively, with a flange, d (1. Flange d is provided with vertical arms 0, to the upper end of each of which an arm, G, is secured.

Arms G radiate from the sleeve, and are curved, as are arms D D, before referred to. Arms G are each provided with a series of notches, f, there being one of such notches for each flap E. The outer end of each arm G rests upon a strip, H, secured each to an upright, K, which connects arms D D at their outer ends. Each strip H is provided with a pin or stud, g, which serves to limit the movement of arm G and keep it from leaving such strip.

Mounted upon flange d of sleeve F is an arm, L, adapted to contact with a lever, M, now to be referred to. Lever H is pivoted at or about its center in one of the braces C.

Mounted upon the lower end of the same brace C there is an arm, N, provided with two studs, h h, with which the lower end of lever M is adapted to contact.

By reference to Figs. 3 and 4 it will be seen that when lever M contacts with stud h its upper end will be in such a position as to be out of line of arm L, while if such lever is in contact with stud h its upper end will be in position to contact with such arm L.

The operation of the device is as follows: The parts being in position shown in Fig. 1, the wind will strike one set of flaps E and force them to a position to form a solid wing, against which the wind will strike to operate the wheel. As the wheel revolves each succeeding set of flaps will be operated in a similar manner, while the wing first operated upon, as soon as it passes the line of the wind, will be opened by the resistance of the wind, carrying the flaps to their original position. During the above operation it will be understood that lever M is in such a position as to be free from arm L. If it is desired to fix the wheel so as not to be operated, the lever M is turned to the position shown in Fig. 4., when upon the first revolution of the wheel arm L will contact therewith and serve to arrest the arms G, which will thus be forced between ilaps E and prevent their closing.

ICO

and vertical flaps pivotally mounted between such arms, in combination with a series of notched arms, and mechanism for forcing such arms between the flaps when desired, as set forth.

2. In a windmill, a series of Wings consisting of arms radiating from a common shaft, and vertical flaps pivotally mounted between such arms, in combination with a series of notched arms, a guide for each arm supported upon the wing-frames, and mechanism for forcing such arms between the flaps when desired, as set forth.

3. In a windmill, a series of wings consisting of arms radiating from a common shaft, and vertical flaps pivotally mounted between such arms, in combination with a series of notched arms secured to a sleeve mounted upon the main shaft, an arm secured to said sleeve, and a pivoted lever adapted to contact 0 with such arm when desired to force the notched arm between the flaps, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
